Ingredient review
Distearyl Lauroyl Glutamate
INCI: DISTEARYL LAUROYL GLUTAMATE
A mild, amino-acid-derived emulsifier that creates stable, creamy textures without stripping the skin.
In plain English
Distearyl Lauroyl Glutamate is a gentle ingredient that helps water and oil mix together in creams and lotions. It is made from glutamic acid (an amino acid) and fatty alcohols, so it is much milder than traditional emulsifiers. It also leaves a soft, smooth feel on the skin without clogging pores or causing irritation.

Quick decision guide
Easy yes for most routines
Distearyl Lauroyl Glutamate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Distearyl Lauroyl Glutamate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic emulsifier created by combining glutamic acid (an amino acid) with lauric acid and stearyl alcohol. It belongs to the family of amino-acid-based surfactants and is known for being very gentle on the skin.
How it works
It reduces the surface tension between oil and water, allowing them to form a stable, uniform mixture (emulsion). This creates a smooth, creamy texture in products. It also deposits a thin, conditioning film on the skin, which helps retain moisture and leaves a soft after-feel.
Pros
Gentle on skin
Derived from amino acids, it has a very low irritation risk, making it ideal for sensitive or compromised skin.
Improves product feel
It creates a smooth, non-greasy texture that spreads easily and leaves a soft, velvety finish.
Cons and cautions
Limited research
Compared to classic emulsifiers like glyceryl stearate, there are fewer independent studies on its long-term effects.
Formula-specific
It works best in oil-in-water creams and may not perform well in very low-viscosity or sprayable formulas.
Best for
- People with sensitive or reactive skin looking for gentle moisturizers
- Anyone who prefers products with mild, amino-acid-based ingredients
Use caution if
- Those with a known allergy to any of its components (very rare)
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. Low irritation and comedogenic risk. No significant safety concerns reported in regulatory or dermatological literature.
Research notes
Amino-acid-based emulsifiers like Distearyl Lauroyl Glutamate are generally recognized as mild alternatives to traditional surfactants. Published studies focus on their low irritation potential and ability to form stable emulsions. More long-term human data would strengthen the evidence base.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. No known restrictions at typical use levels.
- Common uses
- Moisturizers, Creams, Lotions, Sunscreens
- Environmental note
- Semi-synthetic; produced from plant-derived fatty alcohols and amino acids. Biodegradability data is limited but expected to be moderate.
Good to know
- It is often used in 'clean beauty' formulations because it is derived from natural amino acids.
- Despite the long name, it is chemically similar to the amino acids naturally found in skin.
